OpenAtlas and CIDOC CRM class mapping

OpenAtlas uses the CIDOC CRM also in the application but because of contextual differences we needed a more fine grained differentiation. E.g. E33 Linguistic Object can be a source or a source translation which have different forms in different context.
Below you see a mapping between CIDOC classes and use of them in the application.

  • Class: CIDOC CRM class, used also as class_code in database table model.entity
  • System class: used as OpenAtlas class, has a system_class field in database table model.entity
  • view name: used in application to show the corresponding view, if empty it means these entities can't be viewed directly
